I know i'm going to get a fairly decent size storage cabinet for growing, around 60'' high, 30'' wide and a depth of 15'' The price for a metal one is abut $150-$170 at my local office depot, staples, office max, which also offer FREE shipping on this large item!! good for me! But for that price, its a little steep for me, I want to spend more on the growing materials inside! Wood is much cheaper than the metal storage cabinets, and the same size I want to know if using wood would be okay? or metal? their both going to have mylar in them, but I dont know THANK YOU!
